Section 1. A zSeries Linux file system test script

1.1 Overview

I was presented with a question regarding disk space efficiency, small files and block sizes with ext3 file systems on zSeries Linux. I decided to write a simple script to test how many files could be written to two ext3 file systems of the same size with block sizes of 1024 and 4096. I figured it would take a couple of hours.

Then I decided to add the Reiser file system and JFS while I was at it because it should be quick to just add a couple more tests.

I asked a question on the linux-390 list server about 1024 byte block sizes and a lot of other considerations were discussed.

Then I decided to add testing copying different file sizes - 20, 200 and 2000 bytes, given that different file sizes will behave differently.

Then I decided to add using FCP disks instead of the more common ECKD.

Then I decided to test read and write performance, in addition to disk space efficiency.

Now this had turned into more than a couple of hour job. In fact, the script ran for more than half a day. But hopefully the results are worth the effort.

1.2 Setup

The minidisk setup is more traditional than setting up the FCP disk. I created four 500 cylinder minidisks on a z/VM Linux userid, all from the same 3390-3 DASD. The directory statements in the USER DIRECT file are as follow:

MDISK 103 3390 0510 0500 VM5308 MR LINUX390 LINUX390 LINUX390MDISK 104 3390 1010 0500 VM5308 MR LINUX390 LINUX390 LINUX390MDISK 105 3390 1510 0500 VM5308 MR LINUX390 LINUX390 LINUX390MDISK 106 3390 2010 0500 VM5308 MR LINUX390 LINUX390 LINUX390

FCP disks are new to zSeries. I asked the hardware guys for this and they said, "Yes we believe that can be done". Five months later I finally got my disks. To be fair it is a complicated setup and new to S/390 guys. The following script loads the appropriate modules and the specific FCP-accessed disk. Details are outside the scope of this paper.

# cat usefcp#!/bin/bashecho "inserting all FCP/SCSI modules"rmmod zfcpmodprobe qdiomodprobe scsi_modinsmod zfcp map="\0x300 0x01:0x20010060451618C5 0x00:0x0001000000000000"modprobe sd_modmodprobe st

While the fdasd command is used to partition ECKD DASD, the fdisk command is used to partition the FCP disks. I wanted to create them the same size. The assumption used calculates the number of bytes on DASD before issuing the dasdfmt command:

500 cyls * 15 trks/cyl * 56664 bytes/trk = 424980000bytes = 405.3MB

So the value +405m is used with the fdisk command to create 4 primary partitons:

The new partition table is viewed with the p subcommand:

Now the partition table is written with the w subcommand:

Command (m for help): wThe partition table has been altered!

1.3 Assumptions

There are 8 file systems tested - a set of 4 using conventional DASD and a set of 4 using the newer FCP access method.

1.4 The script

Here the script is described. If you want to skip the details and go straight to the results see (xref). First global variables are defined for the devices, both DASD and FCP, and the file system mount points. Also, a variable is defined for the temporary file that will be copied many times.

#!/bin/bash# script to test disk utilization, read/write performance of file systems

# define variables for devices, file system mount points and filesDEV1=/dev/dasdd1DEV2=/dev/dasde1DEV3=/dev/dasdf1DEV4=/dev/dasdg1DEV5=/dev/sda1DEV6=/dev/sda2DEV7=/dev/sda3DEV8=/dev/sda4FS1=/ext3-4kFS2=/ext3-1kFS3=/reiser-4kFS4=/jfs-4kFS5=/ext3-4k-FCPFS6=/ext3-1k-FCPFS7=/reiser-4k-FCPFS8=/jfs-4k-FCPTMPF=/tmp/foo

The function header is defined to print a heading in the output file.

header() { echo "" echo "$1 byte files" echo "==============" }

The function makeDirectories will create empty mount points if they are not already defined.

makeDirectories() {

if [ ! -d $FS1 ]; then mkdir $FS1; fi if [ ! -d $FS2 ]; then mkdir $FS2; fi if [ ! -d $FS3 ]; then mkdir $FS3; fi if [ ! -d $FS4 ]; then mkdir $FS4; fi if [ ! -d $FS5 ]; then mkdir $FS5; fi if [ ! -d $FS6 ]; then mkdir $FS6; fi if [ ! -d $FS7 ]; then mkdir $FS7; fi if [ ! -d $FS8 ]; then mkdir $FS8; fi }

The function unmountFileSystems will unmount any mounted file systems. TODO: test for a bad rc - if a process has one of these as its current directory,

unmountFileSystems() { umount $FS1 umount $FS2 umount $FS3 umount $FS4 umount $FS5 umount $FS6 umount $FS7 umount $FS8 } 8

The function makeFileSystems makes 8 file systems out of the 8 devices. The flag -i 1024 is used with the mke2fs command with ext3 file systems that have a block size of 1024 so as to give them more inodes.

makeFileSystems() { echo "y" > /tmp/yes mke2fs -j -m 0 -b 4096 $DEV1 > /dev/null 2>&1 if [ $? != 0 ]; then echo "1!"; exit; fi mke2fs -j -m 0 -b 1024 -i 1024 $DEV2 > /dev/null 2>&1 if [ $? != 0 ]; then echo "2!"; exit; fi mkreiserfs $DEV3 < /tmp/yes > /dev/null 2>&1 if [ $? != 0 ]; then echo "3!"; exit; fi mkfs.jfs $DEV4 < /tmp/yes > /dev/null 2>&1 if [ $? != 0 ]; then echo "4!"; exit; fi mke2fs -j -m 0 -b 1024 -i 1024 $DEV5 > /dev/null 2>&1 if [ $? != 0 ]; then echo "5!"; exit; fi mke2fs -j -m 0 $DEV6 > /dev/null 2>&1 if [ $? != 0 ]; then echo "6!"; exit; fi mkreiserfs $DEV7 < /tmp/yes > /dev/null 2>&1 if [ $? != 0 ]; then echo "7!"; exit; fi mkfs.jfs $DEV8 < /tmp/yes > /dev/null 2>&1 if [ $? != 0 ]; then echo "8!"; exit; fi rm /tmp/yes }

The function mountFileSystems uses the mount command to mount the 8 file systems.

mountFileSystems() { mount $DEV1 $FS1 if [ $? != 0 ]; then echo "9!"; exit; fi mount $DEV2 $FS2 if [ $? != 0 ]; then echo "a!"; exit; fi


mount $DEV3 $FS3 if [ $? != 0 ]; then echo "b!"; exit; fi mount $DEV4 $FS4 if [ $? != 0 ]; then echo "c!"; exit; fi mount $DEV5 $FS5 if [ $? != 0 ]; then echo "d!"; exit; fi mount $DEV6 $FS6 if [ $? != 0 ]; then echo "e!"; exit; fi mount $DEV7 $FS7 if [ $? != 0 ]; then echo "f!"; exit; fi mount $DEV8 $FS8 if [ $? != 0 ]; then echo "g!"; exit; fi }

The function copyIn copies the temporary files to the directory specified in the first argument ($1) for the number specified in the second argument ($2).

copyIn() { for ((i=0; $i<$2; i++)) do cp $TMPF $1/$i.txt if [ $? != 0 ]; then return; fi done }

The function countFiles counts the number of files after in a file system. This is important after the file systems have been filled to the maximum.

countFiles() { echo "Number of files:" cd $FS1 numFiles=`ls -l | wc | cut -b 1-7` echo "\"ext3\", $numFiles" cd $FS2 numFiles=`ls -l | wc | cut -b 1-7` echo "\"ext3-1k\", $numFiles" cd $FS3 numFiles=`ls -l | wc | cut -b 1-7` echo "\"reiser\", $numFiles" cd $FS4 numFiles=`ls -l | wc | cut -b 1-7` echo "\"JFS\", $numFiles" cd $FS5 numFiles=`ls -l | wc | cut -b 1-7` echo "\"ext3-FCP\", $numFiles" cd $FS6 numFiles=`ls -l | wc | cut -b 1-7` echo "\"ext3-1k-FCP\", $numFiles" cd $FS7 numFiles=`ls -l | wc | cut -b 1-7` echo "\"reiser-FCP\", $numFiles" cd $FS8 numFiles=`ls -l | wc | cut -b 1-7` echo "\"JFS-FCP\", $numFiles" cd /root/ }


The function testDiskSpaceEfficiency continues to copy files until the file system is filled for each of the 8 file systems. The functions unmountFileSystem, makeFileSystem and mountFileSystems are first called to start with clean file systems. The copyIn function is called for each file system for two million iterations, though each file system will fill up much earlier. The time command is used to track the time it takes to fill up each file system.

testDiskSpaceEfficiency()# arg1 - number of 200 byte records in file to be copied { unmountFileSystems makeFileSystems mountFileSystems

echo "File systems before copying:" df | grep -

dd if=/dev/zero of=$TMPF bs=200 count=$1 time copyIn $FS1 2000000 time copyIn $FS2 2000000 time copyIn $FS3 2000000 time copyIn $FS4 2000000 time copyIn $FS5 2000000 time copyIn $FS6 2000000 time copyIn $FS7 2000000 time copyIn $FS8 2000000 rm $TMPF echo "File systems after copying:" df | grep - countFiles

The function testWrite

The function copyOut is called to test the read performance of file systems. The output is simply copied to the null device /dev/null.

copyOut() { for ((i=0; $i<$2; i++)) do cp $1/$i.txt /dev/null if [ $? != 0 ]; then return; fi done }

The function testRead is called

testRead()# arg1 - number of 200 byte records in file to be copied { echo "File systems before copying:" df | grep - dd if=/dev/zero of=$TMPF bs=200 count=$1 time copyOut $FS1 $2 time copyOut $FS2 $2 time copyOut $FS3 $2 time copyOut $FS4 $2


time copyOut $FS5 $2 time copyOut $FS6 $2 time copyOut $FS7 $2 time copyOut $FS8 $2 rm $TMPF echo "File systems after copying:" df | grep - }

Now that all the functions are defined, it’s time to get to work

1.5 The output

The script is run via the nohup command that allows you to log off and still continue the command:

# nohup testfs &

What is worth noting here - ext3 with 1Kb block size on DASD loses almost half. TODO: further analysis (why is ext3-4k almost identical between DASD and FCP?)
